Metal Slug 6

Metal Slug 6 is a run and gun video game for the Sammy Atomiswave arcade platform in the Metal Slug series. It was released in 2006.Metal Slug 6 returns to the Rebel-Martian alliance featured in Metal Slugs 2, X, and 3, but on a much broader scale. Rather than repeating the previous games' events of the Martians breaking the alliance and the Rebels assisting the player in turn, the player now teams up with the Rebels and Martians to combat an even greater threat.There are now two modes of play the player can choose from right at the beginning: Easy and Hard. Easy mode lowers the difficulty of the game and changes the player's default weapon to the Heavy Machine Gun; however, the game ends just before the final mission.
